MODINE, OF RAGINE, WISCONSIN, ASSIGNOR 'I'O MODINE MANUFAGTURING COMPANY, OF RACINE, WISCONSIN, A CORPORATION OF WISCONSIN HEAT EXCHANGE APPARATUS Application filed August 9, 1929. Serial No. 384,732.

The invention relates to heat exchange devices and has among its various objects the provision of a unitary structure whereby a large quantity of one fluid substance is forced into the path of a relatively large moving body of another fluid substance to thereby quickly and economically cause the heat of.

one substance to be transferred to the other to thereby change the temperature of the former.

A further object of the invention is the provision of means whereby a liquid is pumped or otherwise forced into the path of a stream of'fluid to thereby vary the temperature of said liquid or fluid and to providemeans for forcibly causing movement of said fluid relatively to the liquid to thereby facilitate a temperature change of either the liquid or fluid.

Another object of the invention is the provision of a unitary structure which includes a fan, a liquid pump, a. radiator through whichthe liquid is pumped and from which said liquid is delivered to the system and to arrange said radiator with respect to an air duct in which the fan is located so that air is caused to travel through the radiator to thereby reduce the temperature of the liquid as it passes through the radiator.

The invention has these and other objects, all of which will be more readily understood when read in conjunction with the accompanying drawings which illustrate one embodiment of which the invention is susceptible, it being evident that changes and modifications may be resorted to without departing from the spirit of the appended claims forming a part hereof.

In the drawings, Fig. 1 is a side elevation of a unitary structure whereby the above and other objects may be accomplished;

Fig. 2 is a plan view of Fig. 1;

Fig. 3 is an end view of the structure shown in Fig. 1

Fig. 4. is a section taken on line 4-4 of Fig. 2; and

Fig. 5 is a section taken on line 55 of Fig. 4:.

The embodiment of the invention illustrated in the drawings contemplates the use of a fan 10 which is mounted upon an end of the shaft of an electric motor 11. This fan i is rotatably arranged in a fan housing 12 I which is supported by means of the legs -1313 connected with the frame or base 14:

which also provides a means upon which a motor 15 and water pump 16 are mounted. A

member 17 providing an air duct is connected end 20 of the duct 17 is provided with a heat exchange device or radiator generally designated 21 which includes a plurality ofradiator units respectively designated. 22 and 23 including tubes2et having fins 24 to facilitate the dissipation of heat contained in the commodity forced through the heat exchange units 22 and 23 The opposite ends of the units 22 and 23 are respectively connected with headers 25, 26, 27 and 28 which are soldered or otherwise fastened in the opening 20 of the duct 17 The headers 27 and 28 communicate with each other through the medium of the fittings generally designated 29 which may include a union to facilitate connection and separation of the radiator units 22 and 23 from each other should this, at any time, be found necessary or desirable. A pipe connection 30 extends from the lowermost header 26 and extends through the wall 31 of the duct 17 and has a pipe connection 32 connected therewith which completes a connection between the header 26 and the water pump 16. It is understood thatthe water pump 16 has an inlet 33 whereby water being adapted to be connected to any.

structure containinga fluid the temperature of which it is desired to change. These units 22 and 23 are inclined relatively to each other as clearly shown in Fig. 4 to facilitate draining thereof. The tubes of the radiator units ing in combination,

arranged in said housing.

22 and 23 are preferably elongated in cross section as shown in Fig. 5 and the fins 24 are, as also shown in said figure, of a relatively long and narrow character and are of relatlvely thin gauged material so asto more readily conduct heat from the comwhereby a fluid is forced through heat ex:

change units and caused to travel through a path of moving air created by the fan lv which will quickly vary the temperature of theliquid flowing in said units or the air passing through said units and thereby cause the temperature thereof to be brought to the degree desired for the particular use for which it is to be employed.-
